Synopsis

The Present Status Of Visual Science, Issue 27 by Leonard Thompson Troland. This monograph surveys vision as an interdisciplinary science that rests on physics, physiology, and psychology, and it traces the development of visual theories from Greek philosophers and Alhazen to Kepler, Helmholtz, and beyond. It distinguishes two general kinds of facts: physical factors that constitute the visual stimulus and neural transmission, and psychological factors that constitute visual consciousness—the colors, depth, and forms experienced by an observer. It argues for a psychophysical parallelism between these domains and outlines the total visual response as a concatenation of distinct stages: object, stimulus, sense-organ and receptor processes, afferent conduction, central processing, efferent adjustments, and the resulting percepts. It reviews major methods—psychological introspection, physiological experimentation, and psychophysical measurement—and advocates clear terminology (color solid, visual field) and coordinated research. The work also surveys the retina (rods and cones), the ocular media, the pathways to the cortex, and ocular motor mechanisms, and proposes a program for reconstructing the total visual mechanism. A foundational text in visual psychology and physiology.
